Platforms and products is one of four new operating units created in this latest restructuring, which also birthed an advanced technology group, a marketing group and a consumer group. Why this particular arrangement is any better than AMD’s reorg of a year ago–which spawned the Central Engineering Organization and Computing Solutions Group–is anyone’s guess. AMD CEO Dirk Meyer says it will optimize AMD’s operations and drive the company toward sustained profitability and long-term success. But then he said that about the last one as well.

Oh, speaking of that last reorg, Randy Allen, the 24-year AMD veteran who figured so prominently in the company, is leaving. AMD (AMD) offered no explanation for his departure and there’s no word yet on where he’s headed. That said, some surmise that he may be following a path beaten by two of his former colleagues, Raja Koduri and Bob Drebin, who both fled AMD for Apple (AAPL)

Apple (AAPL) won’t say what it is exactly that Drebin’s going to work on, though it’s a safe bet it’s related to the multicore graphics processors in which he has his expertise. After all, Drebin’s the guy that, according to his AMD bio, “led the architecture and design of many of ATI award-winning graphics processors” and “was responsible for the design of the graphics chip used in Nintendo’s GameCube console.” That’s quite a CV and one that suggests he’ll jibe well with the rock-star chip design team Apple brought in-house with its April 2008 acquisition of boutique semiconductor design company, P.A. Semi.

What that team is working on, of course, is anyone’s guess. Perhaps something to power that high-definition, touchscreen e-book reader it’s rumored to be building…
